Direct digital manufacturing also known as DDM is a unique new alternative means of creating finished objects using 3D printing. It is significantly different from traditional manufacturing procedures and eliminates constraints such as injection or pressure molding which these more traditional processes often involve.
Using digital manufacturing it is possible to commence manufacturing immediately the concept design of a model has been completed using CAO software. The production period lasts minutes or hours as opposed to days, weeks or months.
Traditional manufacturing procedures require the creation of expensive tools and molds. Direct digital manufacturing eliminates the need for these significantly reducing manufacturing costs as a result.
It is possible to implement the design of any item conceived by the designer. As a result, innovation is enhanced making it possible to create objects with enhanced capacities for performance.
